FILE-BINDER.

Specification of Letters Patent.

Patented July 26, 1910.

Application led April 4, 1910. Serial No. 553,424.

To all whom it may concern:

Be it known that l, JAMES C. DAWSON, a citizen of the United States, andresident of Webster Groves, county of St. Louis, and State of Missouri,have invented certain new and useful Improvements in File- Binders, ofwhich the following is a specification, and which are illustrated in theaccompanying drawings, forming a part thereof.

The invention relates to that type of le binders which comprise a pairof clamping members, filing posts projecting from one of the plates andslidably engaged by the other, and which are usually provided with coverplates hinged to the clamping members.

The invention relates to an improved form of end cushion for the bindingmembers, its object being to provide a substantial cushion which may besecurely held in place and may be easily removed to be re-` placed incase of wear.

The invention is fully described hereinafter and illustrated in theaccompanying drawings, in which- Figure 1 is a detail plan View of thebase of the binder, the end of the binding member and the cushionapplied thereto being shown in plan section; Fig. 2 is a detailtransverse section of the clamping members on the line 2 2 of Fig. 1;and Fig. 3 is a detail of one of the clamping members on the line 3-3 ofFig. 1.

The clamping members are shown at 10, l1, the one being adapted to carrythe filing posts, one of which is indicated at 12, and the otherconstitutin a follower for running on these posts. ne of the coverplates is shown at 13l as being hinged to the clamping member 10. TheVclamping members are in the form of flat tubes, and to the end of eachthere is tted a cushioning block 14E, preferably of rubber, this blockbeing a little wider and a little thicker than the tube, and beingchanneled in its inner face to receive the end 15 of the tube, thusforming a tenon 16, which fits within the tube, and a jacket 17inclosing the end of the tube.

The cushioning block is secured in place by means of pins 18, each setthrough one of the flat faces of the tube, the pin preferably beingpointed in order that it may be forced into the rubber and providedadjacent its head with an enlarged threaded body 19 for engaging athreaded aperture in the wall of the tube. The head 20 of the pin isliattened and of greater diameter than the body portion 19, and entersan aperture in the outer face of the cushioning block, and is preferablyslotted, as shown, for convenience in application and removal.Preferably two such pins are used in securing each of the cushioningblocks. As thus formed the block may be of comparatively soft rubber,thereby eifectually eliminating the objection to binders of this kinddue to the fact that they mar the desk upon which they are used. Thesize of the block may be such that its tube-envelopingv portion 17 issubstantially of the same thickness as the cover 21 of leather or fabricwhich is ordinarily applied to the outer face of the clamping member,the cover abutting against the inner edge of the cushioning block andforming therewith a smooth surface.

l claim as my inventionl. A le binder comprising, in combination, atubular clamping member, and a cushioning block having a tenon iittingwithin the chamber of the clamping member, and a liange fitting upon theouter face of the clamping member.

2. A file binder comprising, in combination, a tubular clamping memberand a cushioning block having a tenon fitting within the chamber of theclamping member, a flange fitting upon the outer face of the clampingmember, and a pin setting through and in threaded engagement with thewall of the clamping member and entering the tenon of the cushioningblock.

3. In a iile binder, in combination, a tubular clamping member and acushioning block having a tenon entering the end of the tubular member,its body portion projecting beyond the end of such member, and means forsecuring the block to the clamping member.
